Darkpaw

Darkpaw is one of Emerald's main characters, and - as usual for most things that Emerald joins - has been slightly incorporated into Glowaithe, in the forme of a badge. She's a hybrid of the Pokemon Mewtwo, Rayquaza, Giratina and Darkrai.

To obtain, one must know of Darkpaw, or have something they post - this is likely to occur most in Forum Games - countered by Emerald posting 'Darkpaw is cute. Your logic is invalid.' or some variation of it.
